I To all whom it may concern Be it known that I, EDWIN W. FISHBURN, a citizen of the United States, residing in the city and :county of Denver and State of I Colorado, have 'invented'certain new and useful Improvements in Means for Attachming Air-Pumps to Automobiles; and I do declare the following to be a full, clear, and exact description of the invent-ion, such as 10-;

will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification. j

My invention relates to improvements in 7 means for attaching air pumps to automobiles, whereby; by the rotation of one wheel, of'the machine, the tires of the other three wheels may be inflated. The-manner of operation consists in connectin one extremity of an ordinary pump for in ating tires with the foot-board of the machine, and connecting the other extremity with one of the wheels of the vehicle beyond the'cent'er, whereby, as thewheel is rotated by the operation of the engine, the pistons,

carried'by the pump cylinders, will'be reciprocated and air forced through a tube of 30 outer extremity adapted to be connected 7 with the'valves of the tires.

the desired length, carrying a nipple at its In order to operate the pump for inflating threetires of the machine, it is only necessary to jack up the rear axle at. one end, whereby the wheel, which is to serve as the motor, or device for directly operatingthe pump, is raised from the ground Orother surface upon which the machine stands. Then, by; starting the engine, the raised wheel may be rotated. The opposite extremities" of the pump are pivotally connectedwith the 'machine, whereby, as the Wheel.

rotates, the pump may oscillate from its piv- Iotal connection with the foot-board of the In my improved construction, provision is made for adjustably connecting the .plate at-t-he lower extremity of the pump cylinders with the foot-board of the machine, whereby the distance between the center of the wheel,

which is to operate the pump, andthe point of its..connection with the foot-board, may {be regulated at will. This point ofconnec- .tion is determined by the stroke of the pump pistons. In other words, it is necessary to J, so regulate the-connection ofthe pump with :which the cylinders are secured,and the handle connected with the piston rods are readily detachable from the foot-board and the wheel, respectively, This is accomplished through the instrumentality of bolts having hooks at one extremity adapted to engage the spokes of the wheel and winged nuts at their opposite extremities, whereby the bolts are readily adjustable. Similar bolts are also employed connecting the cylinder plate ofthe'pump to the yoke, which is pivotally connected to the foot-board of the machine. -Another set of similar bolts is employed in connecting the yoke with the handle of the pump, the handle engaging extremities of the bolts-being curved to fit the outer extremity of the handle, whereby the handle may turn in the curved portions of the bolts whenever it may be necessary; as, for instance, when the opposite extremity of the pump changes its relative position with reference to the machine. It will be "understood that, in 'som'emachines, the footboard extends farther laterally with referenceto the position of the wheel than in others; consequently, this-movable connection between the handle of the pump and the bolts connecting it with the-pivoted yoke is important.

In my improved construction, the pivot pin,-upon which the cylinder extremity of the pump moves,-is mounted on a metal strap, longitudinally adjustable on a memberclam'ped to the foot-board. It is not always practicable to change the position of the clamp, 'due to the' presence of the tool box or other obstructionaon the foot-board.

By virtue of this adjustable metal strap, the distance between thepivot .at this extremity of the pump and the'axis of the wheel may ibe regulated without changing the position of the clamp. In another form of my improved construction, the pivot pin is mounted at one extremity of the clamp. In this form of constructiomby reversing the clamp, the

opposite pivot pin, or ,that on which the oke.

attached with the handle extremity 0 the pump is pivoted, is mounted near the inner.

edge of a plate, the latter having bolts applied near its outer edgefor connecting the plate with the spokes of the wheel. The distance between the pivotpoint of the plate and the points where the bolts are connected is such that these bolts may be located outside of the band brake of the wheel, while the pivot pin is located between the band wheel of the brake and the axis. By virtue of this construction and arrangement, it becomes practicable to locate the pivot pin for the handle extremity of the pump comparatively near the axle; Thisisimportant, since it is desirable to limit the length of stroke imparted by the wheelto the pistons during the pumping operation.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, referencebeing made to the accompanying drawing, in which'is illustrated an embodiment thereof.

In this drawing: Figure 1 is a fragmentary side elevation of an automobile, showing a pump connected after the manner of my invention. Fig. 2-is a'view looking in the direction of arrow 2, Fig. 1", the parts being shown on a larger scale. In this :view, the foot-board isih'dicated indotted lines, and the clamp, mounted on the foot-board carrying the pivot'pin, is shown in end elevation; Fig. 3 is a view looking in the direction of arrow 3, Fig. 3, the adjustable strap connected with the clamp being broken away, Fig.4 is a detail view of'one oft-he securlng bolts.

Fi 7 is a top view of the same construction, s owing the handle extremity of the pump and the yoke connected therewith.

therefor. Fig. 9'is a side view ofthe pump and its connections, the means for attaching the same to the foot-board of the machine being diiferent from that illustrated inthe other views. Fig. 10'is a view, looking in the direction of arrowlO, Fig. 9.

The same reference characters indicate the Referring first to Figs. 1 to 8, inclusive, let the numeral 5 designate the body of an automobile and 6 one of the rear wheels thereof. To the foot-board 7 on one side of the machine is secured a Ushaped member 8, whose parallel flanges engage the 11 per and lower surfaces, respectively, of the ootopenings 10, formed in the lower flan e of the clamping member, the screws eing caused to enga e the foot-board in clamping relation. To t e outer surface of the clamping member 8 is adjustably secured, by means of bolts 12, a metal strap 13 having a series of openings 14 adapted to register with the two openings in the clamp for the reception of the bolts 12, which are threaded into the outer portion of the clamp, after passing through the strap. Upon the outer extremity of this strap is mounted a pivot pin 15 which engages an opening 16 formed in a yoke 17 attached to the base plate 18 of the pump by means of bolts 19, having parts 20 bent at right angles to the threaded artof the bolts and arranged to en age the ase plate on its surface 0 posite t at to which the yoke isapplied. hen these bolts are tightened by the use of nuts 21, the yoke is properly secured to the base of the pump. In order that the yoke may be adapted for use with pumpshaving base plates of var passed therethrough are, therefore, arranged in staggered relation, whereby their bent portions 20 enga the base plate on opposite sides. By' vlrtue of the fact that these bolts extend beyond the base plate of the 'pump and do not pass therethrough, it is evident that the pump may be connected with the pivoted yoke, without the necessity of boring holes inthe base plate thereof. Th1s 1s considered an important advantage, since the attachment can be made b The handle 4 of the pump, which is se- =cured to the piston rod,2 in the usual man- .ner, 13 connected with a'yoke 26 by means of bolts 24, having curved extremities 25, which engage the opposite extremities of the bandle 1n staggered relation, the said bolts being passed through ears 27 projecting from the extremities of the yoke in o posite directions. This-connection of the'yo e with the handle of the pump is such that the handle mayturif'within the curved portions of the securing bolts, thus making it practi' cable toychange the angle of the pumps direction, wherever' it may be necessary on difl'erent machines, by reason of the fact that the lateral projection of the toot-board varies on machines of difi'erentmakes; This yoke is pivotally connected with ap'late 28,wh1ch is secured togtwo spokes 29 of anv' person, without the assistance of a mec anic.

the wheelat a suitable distance beyond the ",,axle by means of bolts 30, having hook- "shaped extremities 31, which engage the spokes on one side of the plate, the bolt. 1 protruding beyond the oppositeside of the plate and being threaded to receive winged nuts 32, which may be applied by hand, thus making it practicable to connect the plate without employing a mechanic.

The pivotal connection between the plate and the yoke is formed by virtue of a pin '33, which is secured to the plate near the inner edge thereof, meaning the edge nearer the axle of the wheel. The outer extremity 34 of this pivot pin is reduced in size and shouldered to pass through an opening 35, formed in the yoke midway between the extremities of the latter, the yoke being prevented from slipping off the pivot pin by means of a cotter pin 36, or other suitable fastening device.

By virtue of this construction and arrangement, it becomes practicable to so arrange the plate 28 that the pivot pin may be between the brake drum 37 of the wheel 6 and the axle, while the bolts 30 arelocated outside of this drum, thus securing the advantage of locating the pivot pin as near the center of the wheel as desired. This feature is illustrated in Fig. 1, in which the relative position of the plate 28 and the yoke 26, where thepump is connected with the wheel, is disclosed.

In the form of construction illustrated in Figs. 9 and 10, the base plate 18 of the pump is connected with the yoke 16 in substantially the same manner as heretofore described, when referring to the other form of construction. This yoke, however, is provided with ahook38, adapted to interlock with an eye 39 formed on 'the outer extremity of a pin 40, mounted on the clamp .8, being located on one extremity of the said clamp and stationary thereon. By virtue Qfthis interlocking hook-and-eye construction, the position of the pump may vary to harmonize with differences in construction of different machines with reference to the locationof the foot-board and the outer extremity of the pin 33, with which the plate 7 28 is equipped. It will be understood that Under these circumstances, ordinarily the outer extremity of the'pin 33 will project laterally beyond the outer-extremity of the pin 40 mounted'on the clamp 8. Hence, the

necessity-pf a sort of universal joint connection between the base plate of the pump and the pin 40, whereby movement is al- Ilowed both-laterally and vertically. The

vertical oscillation of thepump is necessary during thefrotati'on of the. wheel 6 with which the pump :isconnected. The lateral oscillation or movement is also permitted by virtue of the connection heretofore described.

It Will be understood that, by reversing the clamp 8, the pin 40 will be thrown nearer the axle of the wheel and into the position shown in Fig. 9. When this is done, the top and bottom flanges of the clamp 8 have changed positions. In other words, the flange, which is below when the clamp is arranged as in Fig. 9, will be above the footboard when the clamp is reversed. Hence, it will be necessary to insert the securing screws 9 in the top flange ofthe clamp, when the latter is in the reverse position. This reversing movement of the clamp permits a variation in the distance between the center of the axle and the pin 40 by several inches, which will ordinarily be sufiicient to make it practicableto use a standard conand operation of my improved construction will be readily understood. In order. to operate the pump by means of the wheel 6, the extremity of the axle 41, upon which the operating wheel is located, will be raised from the surface 42 upon which the machine rests, by the use of a jack 43 of ordinary construction. As soon as this is done, the pump is connected with the foot-board by attaching the clamp 8 thereto, assuming that the yoke 17 is first connected with the pivot pin- 15 mounted on the metal strap 13, as heretofore described, the handle or opposite extremity of the pump being connected with the spokes ofthe wheel 6 in suitable proximity to the axle for operating purposes. The engine is then started, whereby the wheel 6 will be rotated to reciprocate the pistons in the pump cylinders 44 and 45. This pump, as illustrated in the drawing, is the ordinary hand pump and may be utilized in connection with my improved attachments, without employing a mechanic to change the pump in any manner whatever. The attachments to the base plate and thehandle of the pump, respectively, may be readily made by any person, since no especial skill is required.
